Zinc oxide nanoparticle reduced biofilm formation and antigen 43 expressions in uropathogenic Escherichia coli
Objective(s): This study aimed to investigate the effect of zinc oxide nanoparticles (ZnO-np) on biofilm formation and expression of the flu gene in uropathogenic Escherichia coli (UPEC) strains. Materials and Methods: Minimum inhibitory concentration (MIC) of ZnO-np was determined by agar dilution method. The effect of MIC and sub-MIC concentrations of ZnO-np on biofilm formation were determin...
متن کاملUnique Properties of Core Shell Ag@Au Nanoparticles for the Aptasensing of Bacterial Cells
In this article, it is shown that the efficiency of an electrochemical aptasensing device is influenced by the use of different nanoparticles (NPs) such as gold nanoparticles (Au), silver nanoparticles (Ag), hollow gold nanospheres (HGN), hollow silver nanospheres (HSN), silver–gold core shell (Ag@Au), gold–silver core shell (Au@Ag), and silver–gold alloy nanoparticles (Ag/Au). Among these nano...

Title of Document: BIOFILM FORMATION BY ESCHERICHIA COLI O157:H7 Karen Suzanne Silagyi, M.S., 2007 Directed By: Associate Professor, Dr. Y. Martin Lo, Nutrition and Food Science Escherichia coli O157:H7 from cattle was evaluated for its ability to produce biofilm on food contact surfaces and quorum sensing signals in various raw meat, raw poultry, and produce broths. Generally, the strain was a...
متن کاملThe ability of uropathogenic Escherichia coli isolates in biofilm formation on urinary catheter and association with bcsA and draE genes
The product biofilm by E.coli strain can cause serious problem for human health. Catheter is considered to be s suitable place for colonization of microorganisms, so that in %5-10 of patients who used catheter for only one day and also in all patients who used it for over 28 days, this colonization of bacteria is observed on catheter. This study is come out in order to compare biofilm formation...
متن کاملEvaluation of biofilm-forming capabilities of urinary Escherichia coli isolates in microtiter plate using two different culture media
The ability of uropathogenic E. coli (UPEC) to cause symptomatic UTI is associated with the expression of a variety of virulence factors. Biofilm formation enables UPEC to resist the flow of urine and increases its tolerance to antimicrobials and the host immune response. The measurement of biofilm formation in vitro is affected by the type of culture medium used. The aim of this study was to e...
